Quick and efficient tech support. Talk to a real human which means the solution or answer to you question is handled quickly. I also like that the emails are cached on the server for 30 days. This saved me recently after a server had failed. It was out of action for over two weeks but i was able to check the cached emails and read them which allowed to me still use the email in a limited fashion. But this was better than not knowing at all. The setup is pretty straight forward and not overly complex. The system activation is super quick as well. This also limits spam and virus as all the emails go through Duocircle filters. This is good as i am not interested in deleting all the spam that would be let through to my server. Review collected by and hosted on G2.com. What do you dislike about Phish Protection by DuoCircle? I use this for a home email server. The price is a bit high when you only have 1-2 users and it is for personal use. I have a few different domains so it can be a bit pricey to do this for all my domains. But from a business point of view i would say the cost is fine. Review collected by and hosted on G2.com. Recommendations to others considering Phish Protection by DuoCircle: I would suggest that if you use this then block your email port (TCP25) on your firewall as that way all your email will be forced through spam gateway which will allow better protection. Review collected by and hosted on G2.com. What problems is Phish Protection by DuoCircle solving and how is that benefiting you? The issue i have is that my ISP blocks port 25 and I want to run my own email server on the same link. This allows me to change the port 25 for SMTP to a non-standard port which is not blocked by the ISP. They also cache emails for 30 days and spam checking. But the main reason was the port forwarding. Note that if you do this you should also block port 25 on your firewall as then spam email senders can't send directly to you as they will not know the non standard port you are using.

Helps eliminate phishing emails from outside sources. Support is very helpful too. Review collected by and hosted on G2.com. What do you dislike about Phish Protection by DuoCircle? The admin panel is a little quirky. Not as intuitive as I would have hoped. You can get things done there, but, the way you do things aren't how you would expect it to behave. Many times a support email is needed for the less than obvious changes. Some users have reported long delays on links to "known" good sites. I think being able to "whitelist" a domain so there is no phishprotect link would be ideal. Review collected by and hosted on G2.com. What problems is Phish Protection by DuoCircle solving and how is that benefiting you? This is a good question. While I think Phish Protection is working, I really can't gauge how effective it's working. If there was a weekly or monthly report emailed to me, then I think I could better gauge what problems/benefits Phish Protect has solved for me. Review collected by and hosted on G2.com.
